They used red and blue symbolism (sparingly) in a similar way where red pill was the opening of the real world oppressed by machines(which had red eyes and pods) and the blue pill was staying in the simulation. Red and blue coloration is extremely common in the japanese works that inspired The Matrix and is present in some ways within the movie, but unlike the things that inspired it, the symbolism feels very half baked and fleeting.
Lain seemed to stick with it even within the most subtle details now that i rewatch it. Like how Taro's navi goggles had red frames but blue lenses and how the user interface of the portable navi used by Nezumi uniquely has both red and blue within it's OS showing his desire to merge the two realities.
